At various points in time, I have tried out various palmtop computers; none have so far proven to be as versatile as pencil and paper. The major problems tend to be:
Keyboards that are too small for adult fingers are not convenient;
Screens too small to contain significant amounts of information are not convenient;
Pen and paper represents a data representation method of almost infinite flexibility; computerized PDAs require more rigid data representations that typically cripples their utility.
There are lots of nifty desktop-computer-based scheduling packages with a plethora of features. They conquer the limitations of the palmtops, unfortunately, they all have the crippling deficiency that they can't remind you anything when you're not at your computer.
I used to use a Franklin Dayplanner. Rather than using the "phone book" that they provide, I periodically print up pages typeset using a document class called addressbk.cls that I wrote up some years ago for LaTeX. I keep a (periodically synchronized-between-home-and work) information list in LaTeX form online, and gradually mark it up with changes. It's not a perfect method, but it has worked fairly well.

Built structure for l2v program to extract vCards from LaTeX document using addressbk.cls.

Wrote team2vcf to convert Lotus Notes export of team list into a vCard file.

l2v produces very nearly correct results; requires only minor filtering code to take out backslashes where (for TeX) special characters required backslashes.

Fixed handling of Doctors and Professors and married people; changed the name to latex2vcf.

There's a bug again with married folk. It now looks up time zone and latitude/longitude based on reasonable guesses of one's city based on address, telephone number area codes, and company names, which is quite cool. The list of cities is pretty limited, but I don't know people in that many cities...
vCard (RFC 6350), vCalendar (Scheduler protocol) These protocols have been standardized through the IETF as protocols for general Internet use for exchange of personal data and personal scheduling data.
A tip of the hat to my brother, Dave, this lists various material about Windows CE. I'm not a fan of Microsoft (nor is he, particularly); if you're into that sort of thing, you might want to visit his site,
This is a rather sophisticated time management package that runs under MS-Windows, and functioned reasonably well under WINE as of October 1997. Offers nice features for juggling tasks into a feasible schedule. Of any desktop-based package, I think I like this one the best.
If it could read and write vSchedule information, thus making it interoperable with other software (generally speaking), it would be even better. It would be similarly superior if it could talk to PDAs like the 3Com Pilot

This package has an exemplary user interface for describing event repetition. The author disclosed the data structures so that one could write one's own programs to manipulate events.
